WHEEL DISK AND THE LIKE.

Application filed November 30, 1921. Serial No. 518,826.

To all whom: it may concern Be it known that I, RUSSELL H. BowEN. a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of. Pennsylvania, have invented certain new and useful Improvements in \Vheel Disks and the like, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to wheel disks especially useful as end or head members of reels, or beams such as employed in connection with textile looms, either for the warp yarns or for receiving the woven fabric.

The primary object of my invention is to enablesuch structures to be expeditiously constructed of sheet metal at a very low cost of production. Amongst the advantages that I aim to secure by my invention are extreme lightness combined with great strength, rigidity against side-wise fiexure, and durability in use.

Other advantages obtainable through my invention will become apparent from my description hereinafter of a. preferred em bodiment.

In the drawings, Fig. I shows a warp beam with end members or heads embodying my invention.

Fig. II is a side view of one of the heads on a larger scale than that of Fig. I.

Fig. III is a cross sectional view taken as indicated by the line III-III in Fig. II; and

Fig. IV is a fragmentary view showing a cross section taken a indicated by the arrows IV-IV in Fig. j I.

The beam head 1 shown in Figs. I, II, and III comprises a pair of disk members 2 and 10, preferably formed from sheet metal by die stamping, and a central hub 20 in i erhe disk 2 is in the main perfectly flat, but has a laterally bent peripheral or circumferential rim or flange portion 3 with a peripheral troughed' depression 4 which, if desired, may be used as a belt groove. Beyond said depression, the flange 3 is bent inward to form an internal annular groove 5 for receiving and securing the periphery of the companion disk 10, as clearly shown in Fig. III. At a region or zone 11 intermediate its center and its periphery, the disk engage the disk 2, and is secured to the latter, at intervals along the region or zone of contact, by rivets 12, 12 having at one end flat heads countersunk in the disk 2, so. as not to mar the flatness or smoothness of the exposed face of the latter. If desired, spot welding may be resorted to at these regions in supplementation or instead of rivetlng. From the zone of attachment 11, the disk 10 is conically flared away from the disk 2 both toward its center and toward its periphery. The disk 10 is stiffened by means 'of a series of uniformly spaced spoke-like radial embossments' 13, joggled or pressed outward in opposition to the dishing, so as to make the disk 1 as a whole stronger and more rigid.

The hub member 20 is axially bored, as a 21, and has cylindrical end portions 22, 23 which project through central apertures 6 and 14 in the disks 2 and 10 respectively. The intermediate portion of the hub 20 is enlarged in the form of a flange 24, which is engaged between the disks as shown in Fig. III. The-hub member 20 may be secured to the'disks by welding, or by riveting as shown at 25, 25, or in both ways.

The double concavity of the disk 10 consequent upon'its being dished as described above gives the structure as a whole great resistance against lateral thrust,-especially thrust upon its flat side at. 2. The lateral strength and resistance of the disk 2 are greatly augmented by the radial embossments or ridges 13. The anchorage or attachment of the disk 10 to the disk 2 at periphery and center (5 and 25) as well as between (at 12) greatly enhances the strengthening and stiffening effect of its configuration.

When used in a beam or reel, the heads 1 are preferably clamped, flat faces innermost, against the ends of the tubular drum or barrel 30, by means of nuts 31, 31 taking on screw threaded portions 32, 32 of a spindle or shaft 33. As shown, this spindle or shaft 33 extends axially through the structure, and has reduced projecting ends 35, 35 to serve as trunnions for rotatively mounting the beam or reel in the bearings of a loom., The hollow drum 30 may be formed of wooden staves secured at intervals to internal sustaining cross webs or diaphragms 36, 36, which are appropriately apertured for passage of the spindle or shaft 33.

Though especially suitable for the heads of a reel or beam, or for a pulley or sheave construction shown may be adapted and applied to various other uses.

Having thus described my invention, I claim:

1. A wheel disk or beam head structure comprising, a pair of sheet metal disks, and a hub interposed between and secured to said disks, one disk being flat and the other expanded to slope obliquely toward the flat disk and contact therewith at points intermediate the hub and periphery to form a shallow annular depression and sloping obliquely away from said flat disk for perimetrical connection thereto.

2.'A wheel disk or beam head structure comprising a pair of spaced sheet metal disks, one having a lateral circumferential flange with an internal ridge defining an outer annular groove, and the other having its periphery engaged and retained in said groove, the latter being expanded inwardly at points between the center and periphery to form an annular depression, and a hub interposed between and secured to said disks.

3. A wheel 'disk or beam head structure comprising, a pair of spaced circular disks, a hub connecting the centers of said disks one disk being flat and having a lateral perimetrical flange, said flange being formed at its extreme edge with an internal annular groove, the other disk having its periphery engaged and retained in said groove, and

expanded toward the flat disk at a point intermediate the center and periphery to form a shallow annular depression having obliquely sloping sides.

4. A wheel disk or beam head structure comprising a pair of sheet metal disks, one being flat and having a lateral peripheral flange, the other being dished toward and secured to the fiat disk-at a region intermediate its center and its periphery and thence flared away both toward its center and toward its periphery, the periphery of said flared disks being secured to the aforesaid peripheral flange; and a hub interposed and secured between said disks.

5.'A wheel disk or beam head structure comprising a pair'of sheet metal disks, one having a lateral peripheral flange, and one being dished toward and secured to the other at a region intermediate its center and its periphery and thence flared away from such other both toward its center and toward its periphery, and strengthened in the region of dishing by spoke-like embossments in opposition thereto, the periphery of one of said disks being secured to the aforesaid peripheral flange of the other;

and a hub interposed and secured between said disks.

6. A wheel disk or beam head structure comprising a pair of sheet metal disks perimetrically joined and their centers in spaced relation, one disk being flat andthe other circumferentially dished inward for attachment'to the fiat disk and strengthened by spoke-like embossments struck outward and intersecting the dishing.

7. A wheel disk or beam head member comprising a metal disk dished circumferentially at a region intermediate its center and its periphery and strengthened by radial spoke-like embossments struck outward in opposition to and intersecting the dishing.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsyl vania, this 28th day of November, 1921.
